Aquaponics is the combination of aquaculture (fish) and hydroponic cultivation of plants. This review examines fish welfare in relation to rearing water quality, fish feed and fish waste and faeces to develop a sustainable aquaponic system where the co-cultured organisms, fish, bacteria in biofilters and plants, should be considered holistically in all aquaponics operations. Water quality param...

The spines of flowering plants are thought to function primarily in defence against mammalian herbivores; however, we previously reported that feeding by Manduca sexta caterpillars on the leaves of horsenettle plants (Solanum carolinense) induces increased development of internode spines on new growth. To determine whether and how spines impact caterpillar feeding, we conducted assays with thre...

Seedlings of aubergine (Solanum melongena L.) cv. ‘Rima’ were used as scion (R) and control (non-grafted) and rootstock (self-grafted) (RR), while two hybrid tomatoes ‘Heman’ (Lycopersicon hirsutm) and ‘Primavera’ (Lycopersicon esculentum) were used as rootstocks. Grafted and non-grafted plants were grown in the greenhouse and in the open-field. Grafted plants Rima and Heman (RH) were more vigo...

In the present study, a field study was performed on some herbaceous plants growing in thesoutheast of Ahvaz, where some metal producing industries are active. The aim of this studywas to investigate and compare manganese (Mn) and zinc (Zn) accumulation in seven dominantherbaceous plants in this area. Plant samples were collected randomly. Associated soils weresampled from the same sites next t...

microbe-associated molecular patterns (mamps) play key roles as activators of the innate immune response in animals and, analogously, as elicitors of defense responses in plants. however, there are not much investigations concerning their real importance in plant resistance against pathogens. here we used derivatives of flagellin and ef-tu as two well-known mamps against some important fungal a...

There are many remediating methods for the polluted soils but only phytoremediation is a cost effective, environmental friendly, aesthetically pleasing approach that is most suitable for many countries. The purpose of this study was to investigate the potential of native plants for phytoremediation of contaminated soils with lead, zinc, cadmium and nickel in the rangelands around National Lead ...

concern about arsenic pollution to soils and plants has been on an increase, throughout the world and an interaction of as with p due to the similarity in chemical characteristics has been also reported. in the present research, a factorial experiment was conducted as based upon a randomized complete block design of three replications including three levels of arsenic (0, 50 and 100 mg kg-1) fr...

For the production of therapeutic proteins in plants, the presence of β1,2-xylose and core α1,3-fucose on plants' N-glycan structures has been debated for their antigenic activity. In this study, RNA interference (RNAi) technology was used to down-regulate the endogenous N-acetylglucosaminyltransferase I (GNTI) expression in Nicotiana benthamiana. One glyco-engineered line (NbGNTI-RNAi) showed ...
